- Abstract:
- The Forest Cottage Gridded Tract is an area just east and north of the Forest Cottage [now called Lyford House]. It comprises part of PH I and PH VIII and includes the Forest Cottage dwelling house. The emphasis of studies initially was on soil and water relationships. Root studies were also made in the vicinity of the Forest Cottage.
